Description

Technical Field

[0001] The invention relates to the technical field of pipeline protection, and in particular to a protection device for a pipeline penetrating a furnace bottom of a gas turbine power plant. Background Art

[0002] A gas turbine power plant is an electricity production facility that uses a gas turbine to generate electricity. Compared with traditional thermal power plants, gas turbine power plants have higher thermal efficiency and lower environmental pollution, and are therefore widely used in modern energy production. They convert the heat energy generated by fuel combustion into mechanical energy to drive the generator to generate electricity. The pipes that pass through the bottom of the furnace in a gas turbine power plant are usually used to transport fuel, cooling media, steam or other fluids to ensure the normal operation and heat dissipation of the equipment. The design and material selection of the furnace bottom through-wall pipes need to take into account harsh working conditions such as high temperature, high pressure and corrosion to ensure their long-term and stable operation.

[0003] However, the existing protective effects of some of the furnace bottom through-wall pipes used in gas turbine power plants are relatively general. In actual use, the surface is usually wrapped with some protective materials. Usually, such protective materials are used to prevent corrosion of the through-wall pipes and also to dissipate the heat on the surface of the through-wall pipes. However, in actual use, these simple methods cannot provide more protective effects for the through-wall pipes. When steam or fluid flows inside the through-wall pipes during use, the through-wall pipes will vibrate. Long-term use will cause the joints of the through-wall pipes to become loose, which requires more energy for maintenance. At the same time, when the pipeline needs to be maintained or replaced, it is not convenient to disassemble the through-wall pipes, which makes maintenance more troublesome. Therefore, it is urgent to solve the above problems. Summary of the invention
